weekend problems

[cyrus]

on all weekends I have problems downloading BBC or Radio Times data. While downloading the data the progress bar stops at "parsing ... data". Staring at Monday everythings works fine again.
Here the error log of today (Saturday):
Couldn't download the program for the whole time!
